Abstract: A data management agent for selective storage re-caching is described. A data management agent with an inter-agent communication link and protocol updates a volume on a primary storage area network connected to the data management agent. The primary storage area network mirrors the update to the volume over a first connection to a corresponding volume on a recovery storage area network. The data management agent further transmits a notification of the update to the volume over a second connection to a recovery data management agent connected to the recovery storage area network. Upon receiving the notification, the recovery data management agent scans only the corresponding volume and selectively refreshes its cached information for the corresponding volume.
